Tour de force analysis of NPN/NPN-O pores
Many thanks to JK, Dean and Gunner (Webster HS) for compiling this table. Take homes … NPN-O has smaller pore sizes, lower porosity than NPN at the same thickness (50 nm). All materials have slightly asymmetric pores (~ R1/R2 = 0.75). Top-side and bottom side pore distributions are not the same. The original NPN material…
